Many statements can be true about those parabolas, so you need to include the list of choices.
This is the list of answer choices that I found for this same question:
<span>A. The second parabola opens downward.
B. The second parabola opens upward.
C. The points of intersection are on the x-axis.
D. The points of intersection are of equal distance from the y-axis.
While A, B or C may be or may not be true, D has to be true.
D. has to be true because the symetry axis of both parabolas is x = 0, so the intersection points will be necesarily to the same distance of the x-axis and the y-axis.
Answer: </span>
<span>The points of intersection are of equal distance from the y-axis.

Answer:
The probability of getting a black pen from the bag is 13.5%.
Step-by-step explanation:
To determine the percentage probability that a black pen will be obtained from the bag, the following calculation must be performed:
12 + 20 + 5 = 37
37 = 100%
5 = X
(5 x 100) / 37 = X
500/37 = X
13.5 = X
Thus, it is determined that the totality of pens is 100%, and through a cross multiplication the percentage of the 5 black pens with respect to the total of pens is obtained.
Therefore, the probability of getting a black pen from the bag is 13.5%.
Answer:
29
Step-by-step explanation:
Use definition of conditional probability:
where
A = the student is a freshman,
B = the student is a male
From the table,
So,
very positive about these results
Well in my calculations I got: well if you he increases the speed by 2.6 per hour soo 4+2.6=6.6
